IMPROVEMENT IN SEED-DRILLS.

To ALL ro WHOM I T MAY coNcnnN:

Be it known that I, HERMON V. DAVIS, of Amherst, in the county ofHillsborough, and State of New Hampshire, have invented a new and usefulimprovement on a machine for ,sowing garden and other seeds, called' aSeed-Drill; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecication, inrwhichi Figure 1 is a perspective and side view, and

` Figure 2 is a top view. v

I construct my machine as follows: I make a piece of wood, a, fourteeninchesl long, two inches wide, and one-half inch thick. On the lower endis a 'seed-box, b, three inches long, one and a half inch high, and twoinches wide, with slide or other cover. I make of thin boards Aa hollowbox or conductor, c, twenty-one inches long, two inches square. `Theaperture is one and a halt` inch wide, and one inch high, three inchesof the upper end of which is filled up. Two and a half inches from thelower end is a partition, d, a little above which is a mortise or hole,e, through the bottom of the conductor c, wherevthe seeds fall into thedrill. .Inst above this, and fastened by screws to the bottom of theconductor c, and extending to the rear, is a small plough, f, madeof'cast iron or some other metallic substance, grooved at the rear end,and two and three-fourths `inches in length, two inches deep;bevel-constructed vso as to pass through the soil freely; and to therear end of the conductor c is attached a coverer made of cast iron, theupper end attached to the lower end of the conductor c by a pin, It,which passes through the sides of the rconductor-r, and through thecovererg, upon which it hangs.' The lower part of thc coverer gis fourinches by two and three-eighths of an inch thick, on the bottom of whichare two wings, zz', ruiming diagonally, as indicated by drawings. To theupper end of the conductor c is attached the piece of wooda; at thelower end of this is attached the seed-box b. This piece a is attachedto the conductor c by a screw, j, passing through it into the conductorc about one inch below theA upper end of the conductor c, and acts as apivot, upon which it vibratesby the motion of the hand. This piece. orhandle a extends eight inches above the upper c nd of the conductor fc,and made of suitable form to be grasped by the hand. Two inches belowthe pivotj is a cross-piece, 7c, fastened on 'each side by screws Z tostuds of iron projecting from each sideof conductor c. yThe object ofthis device is to hold the seed-box b ina proper position upon disk n tovibrate freely. The screws L at each side act Aas. a gauge to thehandleor, which it strikes in its vibrations whenin operation. In the lowercud of handle a, at the bottom of the seedboX 6, isa hole,0three-`ourths of an inch in diameter. Directly under the hole o in theseedfbox l1 is-a thin piece of sheet iron, with a round hole, throughwhich theV seed passes, to protect. the 'wearing of the parts. Justbelow the seed-boi r b, and on the top of the conductor c, is a disk orcircular piece of sheet iron,fn,in the centre of which is a holeiuiwhich is inserted a screw or pin, uponwhich it acts as on a pivot.Toward the outer edge are four or more holes of various sizes, adaptedto the passage of the dierent-sized seeds which passA through them, andin such position that when the disk n is turned, the holes in the diskn', marked severally p pp, come directly under the hole o in theseed-box b, and directly over the hole in the conductor under the bottomof the seed-box. l y

To operate the machine the operator takes hold oi' the handle a anddraws the machine toward him, and at the same time moves the handle aVfrom right to left, and vice versa. The seed-box b being attached, theseed pase down through the hole o and p, falling into the aperture of`the conductor e, then passing out at the hole e, at the lower end ofconductor c, into the groove in the plough f, then falling into thedrill made bythe plough f, then being covered by the coverer g, whichfollows.

What I claim as my invention, and desire to secure by-Letters Patent, is

The several parts, marked a yZ c j' g n 7c, when the several parts Iareconstructed, arranged, and operated as Specified.V
